Madonna and British filmmaker Ritchie hope to have their divorce finalized by Christmas.

They got married in 2000 at a Scottish castle. They have two kids together--Rocco, 8, and David Banda, 3, who was adopted from Malawi. Madonna also has a 12-year-old daughter, Lourdes.

The couple are reportedly worth about $525 million--of course, Madonna earned the bulk of that. They have houses in London, Los Angeles and New York, plus a 1,200-acre estate in the England countryside.

"The judgment of the court would be to try and assess what they came in with and divide what they built up fairly equally," said David Allison, a lawyer.

Ritchie's career took a downturn during the marriage, while Madonna remains wildly beloved worldwide. (Seriously, she has the golden touch.) That might have contributed to their troubles? Maybe he had a hard time being second fiddle?

Are you surprised? Isn't that sad? They seemed like they had a good thing going--she even took on a British accent, like him! What are your thoughts on this? Do you think it's impossible to have a healthy marriage when you're under that much scrutiny? P.S. Madonna is 50, can you believe it?
